UNITED STATES PATENT OFFIC JOSEPH L. MANLOVE,OF MILTON, INDIANA.

GATE.

SPECIFICATION forming part of Letters Patent No. 680,054,0lated August 6, 1901. Application filed ApriI 6,1901. Serial No. 54,687. (No model.)

To all whom itmcty concern:

Be it known that I, JOSEPH L. MANLOVE, a citizen of the United States, residing at Milton, in the county of Wayne and State of Indiana,have invented new and useful Improvements in Gates, of which the following is a specification.

' This invention relates to certain new and useful improvements in swinging gates of that type which are opened and closed by trips located in the roadway to be engaged by the wheel of a vehicle; and the invention consists in the construction and combination of the parts including the make-up of the gatehinges and of a throw-plate with which the lower hinge engages in such a manner that when the throw-plate is moved on its pivot the gate will be thrown out of balance, first releasing the latches and then opening or closing the gate, the gate also being adapted to be opened manually without actuating the throw-plate or trips and when so opened to close automatically, as will be hereinafter set forth.

In the accompanying drawings, Figure 1 is a perspective View of a gate embodying my improvements. Fig. 2 is a side elevation, partly in section, of the upper hinge of the gate. Fig. 3 is a View of the throw or cam plate and its support, the dotted lines showing the range of movement of the throw-plate. Fig. 4 is an end elevation of the trip, and Fig. 5 a perspective view of the lower hingesection of the gate.

The gate A, as shown, has an outside frame made up of gas pipe or tubing, which is braced by a diagonal stay-rod a, which extends from the lower front end of the gate to its upper rear end, said rod passing through an aperture in an elbow-coupling a, the rod being screw-threaded on its end and provided with a nut for tightening the rod. To the frame of the gate are secured vertical rods and horizontal wires, and the top bar may be ornamented by fastening thereto suitable scrolls.

To the gate-post A is secured a casting or hinge-section B, which has therethrough an aperture b and surrounding the aperture a recess 1), in which are placed balls or antifriction-rollers, with which the lower portion of the elbow-coupling a engages. The rear vertical bar of the gate, which is passed through the aperture b, is of less diameter than the aperture to admit of a slight tilting or rocking movement of the gate, and the full weight of the gate is sustained by this ballbearing hinge, the lower hinge or fixture limit ing the movement of the gate and throwing it outof balance when it'is opened or released from its restraining-latch, so that the gate will automatically close. Near the base of the post A is attached a casting 0, having an upwardly-projecting pintle c, which is set on a line with the aperture 1) through the hingesection B.

To the rear lower corner of the gate is secured a fixture D, having studs d d at right angles, and to said studs are secured the rear vertical and the lower horizontal bars of the gate, and rearward of the stud d, so as to extend below the lower bar of the gate, the fixture D has downwardly-projecting pins (P, which enter a space or opening in a throwplate E, so that the pins will lie on opposite sides of a heart-shaped cam E when the gate is closed. The throw-plate E has an aperture 6 through its cam portion, the pin a passing therethrough to maintain the throw-plate in a horizontal position. It will be noted that the side walls of the throw-plate E are spaced so that the pins 01 may be moved forward or away from the post A without imparting to saidthrow-plate any motion which would cause the plate to turn on its supporting-pintle, which would actuate the trips.

The throw-plate E on opposite sides of its pivotal point or aperture 6 has openings e a", with which the trip-rods F F engage, and these three openings e e e are on a line with each other, and in the present case the throwplate is placed so that the opening 6 will be farthest from the post A when the gate is closed, and the gate will be swung away from that side of the plate. The throw-plate may be reversed to cause the gate to open either inward or outward. The trip-rods F F are of different lengths, the longer rod F being on the side of the gateway toward which the gate opens. The rods are suitably supported, and their upturned ends engage the openings e e of the throw-plate, the other ends engaging the crank ends of trips G. The trips are made up from a single bar, which is bent upon itself to provide crank ends 9 with apertures for the reception of the ends of the triprods, and adjacent thereto is a portion which is in line with the inwardly-bent end 9 and over these parts pass loops which hold the trips in place. The parts g g of the double trip are connected by apart or bend 9 which is at an angle of forty-five degrees, so that in operation the parts of the trips which are to the crankends, which are attached to the trip-bars. By this construction the throwplate is turned forty-five degrees in a horizontal plane, which range of movement is sufficientto elevate the front end of the gate a and when its latch is released throw it out of 2 balance, so that it will open, a further turning of the throw-plate merely accelerating The parts operthe movement of the gate. ate in reverse order to close and latch the gate.

To the post A there are attached stops or bumpers hh and a catch-plate h, with which a spring-latch it engages to hold the gate closed. The spring-latch is moved out ofengagement with the catch-plate when the front end of the gate is raised, or the spring may be retracted by operating a bar H, which is carried by the gate so as to project above its upper bar, so placed that it can be readily operated by a person on horseback. I

The bumper-post I on the side of the gateway toward which the gate opens has a catchplate with which the spring-latch engages to hold the gate open.

The construction herein shown providesm-ean-s whereby the gate can beopened by hand without changing the position of the by hand the latch is released by lifting the front end of the gate or by operating the latch-bar, and when the gate is lifted the pins at will be moved forward, and when pressure is applied to open the gate one of the pins will lie adjacent to the end of -the cam, while the other pin moves over the opposite side of the cam, but does not actuate the throw-plate, as said pin moves through the open space. The gate is now edits balance, the rear bar being inclined, and as said gate is maintained by an antifriction-hinge when released it will come to a balance which will automatically close the gate and bring the pins d against the rear inner walls of cam.

the throw-plate, one "on each'side 'ofthe cam. If the gate "should be opened manually for the passage of a vehicle, the vehicle can pass over the first trip' without rocking it, but the second trip will be actuated to close the gate. The throw-plate shown is an improvement over that illustrated in my prior patent, No. 609,035, dated August 16, 1898. The open space being larger is not liable to become vclogged with dirt, snow, or ice, and it is only necessary to finish or smooth the sides of the It will also benoted that the form of the upper hinge is not only better for the purpose, but is also cheaper, as it utilizes a part of the gate and dispenses withone of the fixtures previously used. The construction of the trip is also an improvement, as it dispenses with several parts.

Having thus described my invention, what I claim as'new, and-desire to secureby Letters Patent, is' g d 1. In a gate, a lower or actuating hinge comprising a part having depending pins located near and one on each side of the gate, in combination with an approximately square skeleton throw-plate, having-perforated ears at two of its diagonal corners, and a heartshaped internal cam occupying one of its sides, the depending pins engaging the cam and inner walls of the throw-plate adjacent thereto, said pins being susceptible of movement without actuating the throw=plate, sub-' stantially as shown'and for the purpose set forth. I

2. In a swinging gate, the combination with f an upper hinge which sustains the weight of I the gate, and a lower hinged section having on each side of the gate and in the rear of its pivotal center depending pins, of a skeleton throw-plate or the parts which move in unison therewith. For instance, to open the gate throw-plate which is approximately square the same having perforated ears at two of its diagonal corners, an inwardly-extending heart-shaped cam and straight inner walls on each side of the cam, the distance between the pins relative to the size of the throwplate being such that the gate may be opened and closed without actuating the throw-plate, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH L. MANLOVE.
